1. INTRODUCTION
1.1 PURPOSE OF THIS MANUAL
The purpose of this Manual is to provide information of new User Interface board OMEGA.
1.2 WARNINGS
All work with open appliances must be done with the mains supply disconnected.
The intervention on electrical equipment should only be performed by qualified
personnel.
Before working on a device, check the efficiency of the system housing through means of
appropriate equipment. As an example, refer to the indications described / illustrated in
the portal Electrolux Learning Gateway (http://electrolux.edvantage.net).
After intervention, carry out electrical safety tests and check the correct
operation of all safety devices.
In the case of manipulation / replacement of the PCB, use the ESD kit (Code 405 50 63-
95/4) to prevent electrostatic discharge damage the circuit board see SB No. 599 72 08-09

2.1 RANGE OF APPLICATION AND SPECIFIC FEATURES
There are several variants of ovens and cookers with Vision VCU interface in various structures, combined
with the power board OVC3000 in different aesthetic and brands with the following features:
•Pyro
•Non-Pyro
•Catalytic
•Meat Probe
•Steam
•Microwave
The main features of the Vision VCU interface are:
Full Dot Matrix Display
LCD Modul
same µC family (Renesas) for all interfaces Omega and Vision VCU
flexibility with different glass designs (new designs can be realized very fast)
supports nonPyro, Pyro appliances
supports Steam functionality
supports MW functionality
supports double oven appliance
support 10 digital Inputs for touch sensor fields
2.2 DIFFERENT VERSIONS
RED VERSION (AEG)
White VERSION (ELECTROLUX)
NOTE: The different Hardware versions of Vision VCU Interface through the various software give rise to
different codes programmed interface adapted to the different types and functions of the oven
